To keep the grid frequency very closed to 60Hz (NA) or 50Hz(EU/UK) is critical important for the generator. Frequency Regulation has three different levels. FCR is mainly for “ stop the frequency drift”, aFRR is mainly for “ resolve the frequency drift”, mFRR is mainly for “ fix the primary & secondary ineffective “. aFRR BESS is the most popular requirement from clients, We offer Lithium battery equipped BESS for grid ancillary services it’s from 1hr to 4hrs system. 

Built-in with BESS or stand alone containerized PCS staring from  500KW, up to 3MW, isolated & step-up transformer on-board optional, 10/20/30KV PoC.  IP54 protection, adapt to outdoor harsh environments, high system efficiency, low cost. grid friendly, compensate active and reactive power according to the grid dispatching.

Renewable energy is our future, although these clean energies reduce the active power demand, but not reduce reactive power demand, Utilities and C&I need to configure reactive power compensations to increase power factor if they deployed solar or renewable energy, because higher power factor will reduce waste then increases efficiency. we offer reliable and affordable BESS for C&I applications, such as  reactive power compensation, peak shaving, arbitrage and backup etc..
